Commercial spy Leng Xingchen married into the Ling family in place of the missing orphan "Xing'er".
On their wedding night, she pretended to be a pitiful little white flower to test her husband: "I'm afraid..."
Ling Yao pinched her chin and chuckled: "Madam is very courageous and dares to lie to me."
She sneaked into the study room late at night to steal documents, but found a yellowed group photo in the safe.
The girl in the photo looks exactly like her, and on the back is Ling Yao's handwriting:
"It's time to pay off the debt of the child you saved three years ago."
